Note: post-build and cannainfo.el are necessary only for reformatting one of
the info files whose source was patched, and can go away when the next
minor release (i.e., 2.3) comes out.
@ Don't need freebsd.h and unexsunos4.c anymore (these were taken from
19.28, with a minor modification, which is now known as patch-ac).
@ Tweaked lib-src/Makefile.in.in so that it won't clobber existing emacs
installation (patch-ab).
@ Taken out -g from configure per someone's suggestion (patch-aa).
@ Changed patch site to one in US.
